Following
the non-nuclear war that killed half the world's population, the city-nation
of Olympus stands as a beacon of hope in a world of chaos and conflict.
The utopian metropolis is governed by Gaia, a vast artificial intelligence,
and administered by genetically engineered humanoids known as Bioroids,
whose designer DNA suppresses strong emotions. With Bioroids being half
of its population, peace and order are easily maintained. Deunan, a young
female warrior, and Briareos, a veteran cyborg-soldier, are both partners
and lovers. As members of E.S.W.A.T., the elite special forces serving
Olympus, they are deployed whenever trouble strikes. The two fighters
find their partnership tested in a new way by the arrival of a new member
to their ranks — an experimental Bioroid named Tereus. Created by
Gaia using DNA from Briareos, Tereus uncannily resembles Briareos before
the wartime injuries that led to his becoming a cyborg. Not only does
this trouble Deunan, but Briareos's DNA gives Tereus more than top-notch
fighting skills; this battle-ready Bioroid is like Briareos in another
way — he has also strong romantic feelings for Deunan!
